Perhaps you should try some spelling variations:
"literaturas un debate." » "literatura un debate.", "literaturas en debate.", "literaturas sin debate.", "literaturas el debate."
"literatura e debate." » "literatura en debate.", "literatura del debate.", "literatura el debate.", "literatura a debate."
"literatura de debate." » "literatura del debate.", "literatura el debate.", "literatura en debate.", "literatura den debate.", "literatura da debate."

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("literatura e debate.") OR ("literatura de debate."))) or ("literaturas un debate."))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("literatura e debate.") OR ("literatura de debate."))) OR ("literaturas un debate."))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"literatura e debate.\") OR (\"literatura de debate.\"))) or (\"literaturas un debate.\"))*".
• Removing quotes may allow a broader search: (((( literatura e debate. ) OR ( literatura de debate. ))) or ( literaturas un debate. ))*.
